Since November, the also-pay-what-you-can Speakeasy Series (suggested donation $10-$20) has brought local historians, tour guides and experts on this, that and the other to the Room 13 Speakeasy in Lakeview to learn about topics from Chicago’s bar culture to its history of segregation, from the old Great Central Market to queer history and the development of the skyscraper.

Tomorrow night is the last of the 2017-18 Speakeasy Series. It’s going to be a debate. And I’m in it.
